Abstract: Techniques are provided herein for receiving at a video processing device color video frames comprising grayscale components and color components. The grayscale components corresponding to each of the color video frames are extracted as each of the color video frames is received to obtain grayscale video frames. The grayscale video frames are transmitted at a first transmission rate. Color components for selected color video frames are periodically fused with selected grayscale video frames to obtain fused color video frames, and the fused color video frames are transmitted at a second transmission rate interspersed with the grayscale video frames transmitted at the first transmission rate.

Abstract: A control part 210 sets up an exposure condition under which the bright part of the object is properly exposed and an exposure condition under which the dark part of the object is properly exposed. The control part 210 controls the first and second imaging part 110 and 120 to capture images with the set exposures, whereby a pair of images captured with different exposures is obtained. The control part 210 extracts corresponding points that are characteristic points corresponding between the image pairs. The control part 210 optimizes the extracted corresponding points based on the density of corresponding points between the images constituting an image pair captured with the same exposure and based on the pixel value of the corresponding points between the images captured with different exposures. The control part 210 creates 3D modeling data using the optimized corresponding points.

Abstract: Techniques for estimating global motion parameters based on block-based motion vectors are described. Horizontal and vertical motion parameters are estimated independently. A video processing device, in one example, generates horizontal motion parameter candidates for each row and vertical motion parameter candidates for each column, and selects the median of the horizontal motion parameter candidates as the global horizontal motion parameter and the median of the vertical motion parameter candidates as the global vertical motion parameter. The video processing device may further eliminate candidates by calculating error values for each candidate and remove those candidates with error values below an error threshold. The video processing device may also use pre-calculated values of matrices when calculating each of the candidates to further improve efficient calculation of the global motion parameters.

Abstract: Implementations may relate to various aspects of modifying, or using, a coded bitstream, or to recovering watermarking information from data. In one implementation, a coded bitstream is modified to allow for the application of a watermark to the coded bitstream without changing the coding of any other syntax elements in the bitstream. This is performed by identifying conditions necessary to change a coded syntax element without disrupting the interpretation of subsequent coded elements. The coded syntax element is replaced with another coded value if the modified value generates the same decoding variables as the original value would have generated. Particular implementations focus on syntax elements coded using entropy coding, including, for example, Context-based Adaptive Binary Arithmetic Coding (CABAC). Regardless of the type of coding or watermarking, various implementations may provide for recovering watermarking information.
